Don’t be so positive.

I never knew Yoda was such an accomplished mathematician...

Tbf it can sometimes be difficult to understand him

You just spoke the "|" in "|X| = 3" silent.

That additionally would imply an uncountably infinite set of complex solutions.

[–] FishFace@piefed.social 5 points 3 months ago* (last edited 3 months ago) (1 children)

Why assume the solution is in the complex numbers, and not in

  • the real numbers (2 solutions)
  • the algebraic numbers (countably many)
  • the natural numbers (1 solution)
  • the complex surreal numbers (proper-class many)

Gotta use some context to interpret these things :)

Well it's not physics. Show 'em what happens when you don't specify those kinds of things.

[–] FishFace@piefed.social 1 points 3 months ago

I don't think teachers need to specify that answers should be in the largest class of numbers students have been introduced to so far at school :)

If students are smart and motivated enough to learn about other stuff outside of school, they're smart enough to interpret the question.

My group theory teacher:

"Always two, there are [except in the degenerate case where a = 0]."

"Minus zero" redirects here; not to be confused with Godzilla Minus Zero.

Well thanks Wikipedia!

What are you, IEEE floating point? https://en.wikipedia.org/wiki/IEEE_754

Edit: actually read the negative zero article and saw IEEE floating point mentioned.... kinda kills the joke

[–] OpenStars@piefed.social 4 points 3 months ago

You dare speak of the degeneracy!? 🤪

[–] xia@lemmy.ca 17 points 3 months ago

It's so unnatural...

Unless you want to quote the movie

X^4-6^ were better.

The dark side of multiplication leads to many powers the Jedi consider unnatural
